Evolutionary Genetics Flashcards
what was the significance of finding Oetzi remains in a glacier
we were able to analyse the DNA to discover he died 5300 years ago
how quickly can DNA sequencing analyse a genome
a few hours (costs £1000)
fossil and other evidence suggests that Neanderthals and modern humans coexisted in Europe how recently
30,000 years ago
where are humans thought to have first evolved
Africa
how was evolution discovered and researched
comparative physiology and fossil evidence
DNA difference reflect evolutionary history and allow us to track what
sequencing changes
what suggests humans and apes are related
morphology
why is the human population less genetically variable
since the population is so large and so there is not enough time for variation to occur between generations
name the most isolated population on Earth
Tristan du Cuhna (population= 264 but is descended from 15 ancestors)
what type of population demonstrates a genetic founder effect
isolated populations
within isolated population which disease demonstrates the relatedness of everyone
asthma (23% have asthma with 57% showing symptoms)
